circulatory podcast

The podcast is about the circulatory system. The circulatory system is responsible for transferring blood throughout the body, delivering oxygen and nutrients, removing waste, and fighting diseases. The main parts of the circulatory system are the heart, blood, arteries, veins, blood vessels, and capillaries. Cardiovascular diseases like heart attacks can affect the heart. Blood is made up of plasma, red blood cells, white blood cells, and platelets. The plasma is a liquid that transports substances throughout the body. Red blood cells transport oxygen, white blood cells defend against infection, and platelets are involved in blood clotting. The heart has four chambers: the right atrium, right ventricle, left atrium, and left ventricle. The atria receive blood, and the ventricles pump blood throughout the body. Valves in the heart ensure that blood flows in one direction. good night everyone welcome to the heartbeat hub podcast i'm your host kenzie tonight we'll be talking about the circulatory system and our guest is no other than camilla mckenzie so camilla what is the circulatory system so my idea is that the circulatory system also called the cardiovascular system or the vascular system is a network of organs and vessels that transfer blood throughout the body which is responsible for delivering oxygen and nutrients to cells removing waste products and also fighting diseases okay so the main parts of the circulatory system are the heart the blood the arteries the veins the blood vessels and the capillaries and i'll tell you a little bit about the heart so the heart is the main organ in the circulatory system it is muscular that and it also pumps blood throughout the body and let me talk about the blood vessels the blood vessels entails the arteries the veins and the capillaries which also helps the circulation of blood in the body as well the heart there not the heart the veins itself towards the heart and the arteries pump the blood away from the heart and the capillaries they're tiny vessels that connect arteries and the veins allowing oxygen and nutrients to pass into the tissues and the waste products to leave the tissues okay interesting interesting so when you said the body fights against diseases where are some diseases found in the heart so some you have some cardiovascular diseases like heart attack and coronary heart diseases that you can get that is related to the circulatory system okay so a very very puzzling question for everyone so do you think heartbreak can be a heart disease i don't necessarily think heartbreak can be a heart disease it's probably just some emotions that person feels if they lost a loved one or they are they broke up in a relationship i don't think it's a disease so now we're moving on to the components of the blood so blood is a specialized fluid connect as a specialized fluid connective tissue that circulates throughout the body performing many essential functions it is made up of four main components the plasma the red blood cells the white blood cells and the platelets come on tell us a bit about the plasma so the plasma is a strong colored liquid that is used that makes up about 65 percent of the whole blood it is mostly water around 92 but also contains dissolved protein electrolytes which are salts and minerals nutrients such as glucose amino acids and lipids which are simple facts it also have hormones enzymes and waste products plasma also transport these substances throughout the body and when we talk about the red blood cells it's the most important for these cells these red cells transport the oxygen that our body needs to circulate and keep our body functioning so the red blood cells also called the ether sites are the most abundant type of blood cells they make up about 45 percent of the whole blood and are responsible for carrying oxygen throughout the body their red color comes from a protein called a hemoglobin which contains iron and binds to oxygen molecules in the lungs the red blood cells are we call them the rbc's are produced in the bone marrow and have a lifespan of about 120 days 120 days to hear that so next we have the white blood cells or the wbc's as we call them they're also called the leukocytes and are part of the body's immune system and defend against infection and diseases so like when you have a cold when you have a cold that means the immune system is weak and the white blood cells are strong enough to fight against that cold so they make up of less than one percent of the whole blood but can increase in number in response to the infection so in response to the the type of illness they have so there are several functions several types of wbc's each with a specific function next we have the platelets the platelets are tiny cell fragments much smaller than blood cells that are involved in blood clotting so when you get a cut so they help to show you that the cut doesn't bleed out that means you leave you to die so they help to seal wounds and prevent excessive bleeding platelets make up a very small portion of the whole blood about 0.5 percent that's that okay so thank you so much camera do not move do not go anywhere we're going to take a short break and after the break we'll be talking about the chambers of the heart so so there are four chambers of the heart you have the right atrium the right ventricle the left atrium and the left ventricle so most people don't know that your right side is actually the heart left side and your left side actually the heart right side so as i was saying there are four chambers the upper two upper chambers are called the atria and the two lower chambers are called the ventricles they work together in a specific order to pump blood through the body the right atrium which is upper right chamber it is oxygen depleted blood returning from the body through two large veins the superior vena cava and the inferior vena cava next we have the right ventricle the lower right ventricle pumps the oxygen depleted blood to the lungs for oxygenation oxygenation the left atrium the left atrium upper left chamber receives oxygen rich blood returning from the lungs through four pulmonary veins at the left ventricle which is the lower left chamber which is the thickest and the most muscular chamber of the heart it is the thickest and the muscular part of the heart because this part is that pumps the blood throughout the body so it has to be thick so that the pressure the amount of blood that is coming through so it is the most thickest and most muscular chamber of the heart it pumps oxygen rich blood through the body through the aorta and the aorta is the largest artery in the body and i did not mention this but the vena cava is also the largest vein in the body so to continue the aorta and the ventricles and each cell of the heart are separated by walls and equipped with valves valves are some small things in the heart which ensure that blood flow in one direction only so they don't meet which would be dangerous for the body so basically the valves are in the mass of blood thank you so much camilla thank you so thank you guys so much for joining our heartbeat hub podcast and thank you so much camilla for joining me tonight i hope you learned something new about the heart the circulatory system then i'll be tough like it's the command the cardiovascular system and the chambers and the ventricles and the aorta and the valves and all that so thank you so much for joining see you again next week same time same place on the on the heartbeat hub podcast
