Major components and functions of Blood
The Components of the blood are red blood cell used for respiratory gas transport, white blood cells for helping fight away diseases and infections, platelets used for stoppage of bleeding and plasma which is the liquid matrix.
The major functions of blood are to transport oxygen and nutrients to the tissues and carrying antibodies that help fight infections and help clean out the body by transporting blood
ABO, Rh blood types
There are 2 ways in which an Rh-negative individual can have
contact with Rh-positive blood: a transfusion or pregnancy
If an Rh-negative woman carries an Rh-positive baby, she may be
exposed to the Rh-positive blood during delivery:
ABO Blood- The ABO blood groups are based on presence or absence of 2 important antigens on RBC membranes antigen A and antigen B
Major functions of the cardiovascular system
The cardiovascular system delivers oxygen, nutrients, hormones, and other important substances to cells and organs in the body. It plays an important role in helping the body meet the demands of activity, exercise, and stress.
Anatomy of the heart (including all chambers, and valves)
Your heart is divided into four chambers. You have two chambers on the top (atrium, plural atria) and two on the bottom (ventricles), one on each side of the heart. Right atrium: Two large veins deliver oxygen-poor blood to your right atrium. The superior vena cava carries blood from your upper body
Layers of the heart
The wall of the heart separates into the following layers: epicardium, myocardium, and endocardium. These three layers of the heart are embryologically equivalent to the three layers of blood vessels: tunica adventitia, tunica media,
Blood flow through the heart and body
Blood comes into the right atrium from the body, moves into the right ventricle and is pushed into the pulmonary arteries in the lungs. After picking up oxygen, the blood travels back to the heart through the pulmonary veins into the left atrium, to the left ventricle and out to the body's tissues through the aorta
Structural and functional differences between blood vessel types (arteries, veins,
capillaries)
Arteries carry blood from your heart to your organs. Capillaries transport blood between arteries and veins. Arteries are the largest blood vessels with the thickest walls, and capillaries are the smallest. Arteries are only located deep inside your muscles, but capillaries are inside tissues all over your body
Cardiac cycle and the ECG
Electrocardiogram (ECG) of cardiac cycle: The ECG is a general clinical device used to measure the electrical activity of the heart. This device records the small extracellular signals which are produced by the movement of cardiac action potential through the transmembrane ion channels in the myocytes.
Major blood vessels (names arteries and veins)
The great vessels of the heart include your aorta, pulmonary trunk, pulmonary veins and vena cava (superior and inferior). They connect directly to your heart and play a vital role in your circulatory system.
Vital signs (BP and Pulse)
Normal vital sign ranges for the average healthy adult while resting are: Blood pressure: 90/60 mm Hg to 120/80 mm Hg. Breathing: 12 to 18 breaths per minute. Pulse: 60 to 100 beats per minute
