PE Test 4 Section 1 Flashcards

What function do capillaries serve in the cardiovascular system? (Select all that apply)

All cardiovascular diseases are caused by poor lifestyle choices.

Arteries carry oxygen-rich blood to capillaries.

The aorta pumps blood out of the heart to the rest of the body.

Once entering the nose, air moves through both the pharynx and larynx.

Air is warmed and moistened as it moves through both the mouth and nasal passages.

In the human body, the larynx is attached to the trachea.

White blood cells prevent the loss of blood by causing clotting.

The human cardiovascular system is considered closed because __________.

The right ventricle transports oxygenated blood to the lungs.

Each lung is fed oxygen by a separate bronchus.

Nutrients and waste both enter and leave cells through a process called __________.

Your friend Amanda suffers from a condition that reduces her blood's ability to carry oxygen. Which of the following is the name of that condition?

Both the heart and arteries contract to pump blood throughout the body.

What percentage of blood is made up of plasma?

Cardiovascular System Functions

Capillaries play a crucial role in helping to control body temperature.
Arteries are responsible for carrying oxygen-rich blood to capillaries.
The aorta is the primary vessel that pumps blood out of the heart to supply the body.

Respiratory System Pathway

Air enters the body through the nose and subsequently moves through the pharynx and larynx.
Both mouth and nasal passages serve to warm and moisten the inhaled air.
The larynx is anatomically connected to the trachea, facilitating air passage to the lungs.

Blood Composition and Function

White blood cells do not cause clotting; their main role is to combat infections.
The cardiovascular system is termed 'closed' as blood circulates without entering or leaving the system through openings.
The right ventricle is responsible for transporting deoxygenated blood to the lungs, not oxygenated blood.

Lung Anatomy

Each lung receives oxygen supply through separate bronchi.

Cellular Processes

Cells utilize diffusion for the exchange of nutrients and waste products.

Conditions Affecting Blood Oxygenation

Anemia is a condition that reduces the blood's capacity to carry oxygen, often characterized by low hemoglobin levels.

Heart and Artery Functionality

Both the heart and arteries synchronize their contractions to ensure effective blood circulation throughout the body.

Blood Plasma Composition

Plasma constitutes approximately 55% of total blood volume, serving as the liquid medium for blood cells and nutrients.
