Semilunar valves
________ are found within the pulmonary arteries and the aorta.
Lymphocytes
________- produces antibodies and antitoxins.
Haemoglobin:
iron containing pigment pick Oxygen and drops.
Septum
________: Muscle wall that seperates two sides of the heart preventing the mixing of oxygenated and deoxygenated blood.
Aspirin
________: Dilutes blood and so reduces blood clotting.
Plasma
________ is forced out of the capillary to become tissue fluid.
Muscle cells
________ in the heart need their own supply of blood to deliver oxygen and glucose.
Arterioles
________: Smaller branches of an artery that eventually form capillaries.
Coronary bypass surgery
________: Piece of blood vessel is taken from patients lef or arm.
Mammals
________ have double circulation and a 4 chambered heart.
Venules
________: Small vessels formed from the joining of the capillaries and combine to form a vein.
blood flows
Deoxygenated ________ from the body to the right atrium through the vena cava.
Angioplasty
________: Catheter threaded through the groin up the blocked vessel.
Walls of capillaries
________ are thin; water dissolved substances can easily leak out of them.
Valves
________: Prevent the backflow of blood and ensure one way flow.
Sensitive cell membrane detecs chemicals
________ produced by pathogen.
coronary arteries
Blood is supplied by ________.
Platelets
________ release chemicals that stimulate the conversion of**== soluble fibrinigen → Insoluble fibrin,==** forming insoluble mesh trapping RBCs and froming a clot.
Main artery
Aorta
Shunt vessels
________: Connect blood directly from arterioles to venules forming an alternative route dor blood flow.
Ventricles
________: Have a thicker muscle wall than the atria because they pump blood at higher pressure.
right ventricle contracts
The ________ (semilunar valve opens) blood is pushed through semilunar valves into pulmonary artery.
‘ Leaky walls
________ allow blood plasma to leak out and forn tissue fluid surrounding cells.
lymphatic system
The ________ is composed of lymphatic vessels which carry "lymph "and lymph nodes which produce lymphocytes for immunity.
Arterioles
________ have muscular /elastic walls that can constrict & dilate in order to regulate blood flow.
Circulatory system
System of blood vessels with a pump and valves to ensure one way flow of blood
RIGHT
recieves deoxygenated blood from body (atrium) pumps to the lungs (ventricle)
LEFT
revieves deoxygenated blood from lungs (atrium) pumps to body (ventricle)
Veins
Carry blood towatds the heart
Septum
Muscle wall that seperates two sides of the heart preventing the mixing of oxygenated and deoxygenated blood
Ventricles
Have a thicker muscle wall than the atria because they pump blood at higher pressure
Atria
The right and left atrium contracts to pump blood into the right and left ventricles respectively
Valves
Prevent the backflow of blood and ensure one way flow
Anaerobic Respiration
Glucose→Lactic acid
Aspirin
Dilutes blood and so reduces blood clotting
Angioplasty
Catheter threaded through the groin up the blocked vessel
Coronary bypass surgery
Piece of blood vessel is taken from patients lef or arm
Arterioles
Smaller branches of an artery that eventually form capillaries
Venules
Small vessels formed from the joining of the capillaries and combine to form a vein
Shunt vessels
Connect blood directly from arterioles to venules forming an alternative route dor blood flow
Red Blood Cells
Transport Oxygen from lungs→Respiring tissues
Plasma
Transporting carbon dioxide, digested food, urea, hormones and heat
Plateles
Blood clotting
