Q

Red blood cells are also called

A

Erythrocytes

17
Q

This pigment is located in red blood cells

A

Hemoglobin

18
Q

This number indicates pressure when the heart is at rest

A

Diastolic Pressure

19
Q

This number indicated pressure when the heart is contracting

A

Systolic Pressure

20
Q

This valve is located between the right atrium and right ventricle

21
Q

These particles in the blood are involved in clotting

A

Thrombocytes (Platelets)

22
Q

Starting with the SA node, describe how the heart contracts

A

An electrical impulse starts in the SA node. IT spreads to the atria causing them to contract. The signal then reaches the AV node. Which then travels down the bundles of HIS and stimulate the ventricles to contract. Pumping out of the heart.

23
Q

Write the path that blood flows through the heart beginning with deoxygenated blood entering the heart. Include valves and vessels leading into and out of the heart.

A

Superior Inferios/ Vena Cava - RA - Tricuspid - RV - Pulmonary

Valve - Pulmonary Artery - Lungs - Biscuspid - LV - Aortic Valve - Aorta - Body

24
Q

Describe the two different paths that blood takes through the body. What occurs during each path?

A

Heart - Body - Heart = Delivers oxygen to cells and picks up wastes
Heart - Lung - Heart = In lungs CO2 + H2O released and O2 picked up

25
Q

Name the vessels that blood flows through from the heart of the body and back to the heart

A

Aorta - Heart - Arteries - Arterioles - Capillaries - Venules - Veins - Superior inferior/ VC - Heart

26
Q

Differentiate between veins, arteries, and capillaries in terms of structure and function

A

Veins - Carry blood towards heart
Arteries - Carry blood away from heart
Capillaries - Gas exchange occurs with body cells
Arteries are thicker. Veins are thinner. Capillaries are 1 cell in thickness.

27
Q

In which body cavity is the heart located?

28
Q

Name the layers of the heart starting with the inside layer and working outward

A

Endo, Myo, Epicardium

29
Q

Which layer contains branching cardiac muscle

A

Myocardium

30
Q

Which layer contains endothelial cells

A

Endocardium

31
Q

Which layer for does the pericardial sac adhere to

A

Epicardium

32
Q

Where is the pericardial fluid located and what is its function

A

Space between parietal and visceral. Prevents friction between the two membranes

33
Q

What string-like structures connect the flaps/cusps of the valves to the heart muscles tissue

A

Chordae Tendineae

34
Q

What is the function of the heart valves

A

To make sure blood flow goes in the right direction

35
Q

Describe the route that the blood takes through the heart. Begin where deoxygenated blood enters and end with oxygenated blood leaving the heart. Include the names of any valves, arteries, and veins that are part of this process

A

The deoxygenated blood enters to the right atrium and goes through the tricuspid valve to the right ventricle. Then it goes to the pulmonary vein to the lungs.
When oxygenated blood enters it goes through the left atrium to the left ventricle. It passes through the bicuspid valve out aorta to body
