Chambers of Heart

LORD - Left Oxygenated, Right Oxygenated
Pulmonary Blood Vessels:
-
-
Veins commonly carry de-oxygenated blood but the definition of the vein states that it carries blood away from the heart. The same concept applies to the arteries.

Bones, Muscles & Joints
Bones
-
Short - Roughly cube shaped, provide support and stability (Eg. wrist bones)
Flat - Thin and flat, provide protection to organs (Eg, Ribs, Sternum)
Irregular - No particular shape, provide support and structure (Eg. Pelvic Bones, Veterbrae)
Muscles
Skeletal - Attached to bones, voluntary (Bicep, Tricep)
-
Cardiac - In heart, involuntary

Blood Vessels
Artery
Carries blood away from the heart. Thick wall with elastic fiber to withstand high pressure blood from the heart. Small lumen. Largest - Aorta, Smallest - Arteriole. Blood in artery is usually oxygenated with pulmonary artery as exception. Diverge and get smaller
Veins
Veins carry blood to the heart. Thin wall with valves to prevent backflow from low pressure blood. Large lumen. Largest - Vena Cava, Smallest - Venule. Blood in veins is commonly deoxygenated with exception of pulmonary vein. Merge and get larger.
Capillaries
Meeting point between arteries and veins. Same size. Capillaries are when substances enter and exit the blood. One cell thick walls to ensure permeability allowing for efficient diffusion of vital substances such as oxygen. High surface area::volume ratio. drop off O2, pick up CO2

Components of Blood
-
Plasma
Plasma is 55% of blood. It has a straw-yellow color. It is responsible for the transport of nutrients, hormones and protein. It also plays a role in excretion.
Platelets
Platelets are fragments of cells. They clots blood and are essential to the formation of scabs. Platelets are needed for the formation of fibrin, which is the protein required for clotting of blood. Platelets are needed to prevent pathogens from entering the blood stream and causing harm.
RBC
RBCs have a bi-concave shape, creating a large surface area allowing for optimal diffusion. RBCs are responsible for the transportation of oxygen. RBCs are eukaryotic, allowing them to hold more oxygen in the space the nucleus would take. They contain hemoglobin which combines with oxygen to form oxyhemoglobin
A centrifuge is a machine that rapidly spins objects to separate substances based on their density. In medical settings, centrifuges are commonly used to separate blood components like plasma, red blood cells, and platelets for diagnostic and research purposes. This separation enables various medical tests and analysis to be conducted accurately and efficiently.
