Biology Chapter 22 Test Review
The heart is divided into the left and right halves by the
septum I like to think of sep(arate)tum
The average human lung capacity is about _____ L
4.5
Which of the following happens as a person breathes in?
All of the above (the diaphragm contracts, the muscles between the ribs contract, and air pressure in the lungs lowers)
Which of the following does blood transport in addition to oxygen?
All of these (carbon dioxide, nutrients, waste products)
Why do most people have three loads in the right lung and only two in there left?
Because extra space is allocated to the heart in the chest cavity.
Hemoglobin is a molecule that can carry ________
Both a and b (oxygen and carbon dioxide)
The trachea branches into two ______________ before entering the lungs
Bronchi
Why doesn't drinking carbonated beverages elevate the levels of carbon dioxide in your blood?
Carbon dioxide is being ingested, not inhaled, which means that it is passing through the digestive system, not the respiratory and circulatory systems.
In which respiratory organ are the vocal folds located?
Larynx (remember, silly songs with LARYNX) 😂
Carrying oxygen to cells
Erythrocytes
Sound is produced by the vocal folds, located in the epiglottis
FALSE! That is so wrong! It's the larynx, not the epiglottis!
Both arteries and veins have valves ensure that blood flows in only one direction
False
The heart consists of four chambers: two ventricles that receive blood entering the heart, and two atria that pump blood out of the heart
False
The brains' respiratory center monitors the level of oxygen in the blood
False!
The oxygen transported by blood is used by the body's cells to produce energy from glucose during cellular respiration
True
And whoops, I just realized that Olivia made one too... 😂
Haha
Why is hemoglobin ideally suited as a gas-exchange molecule?
Hemoglobin can carry both oxygen and carbon dioxide at the same time
During expiration, the diaphragm and rib cage muscles relax, causing _______________ pressure in the lungs
Higher
The supplying of oxygen to cells within the body is known as ___________
Inspiration
Why does oxygen in the air in the lungs and move into the bloodstream?
It diffuses from a region of high to a region of low concentration
90% water
plasma
The amount of air that a person can forcefully breathe out after first breathing in as much as they can is known as that person's ____________________
Lung capacity
Which of the following is not a structure or tissue found within the circulatory system?
Lymph node
By volume of the largest component of blood is
plasma
Transporting nutrients and hormones
Plasma
Which loop of the circulatory system transports blood to and from the lungs?
Pulmonary circulation
Which of the following correctly traces the flow of blood to the heart and the lungs?
Right atrium, right ventricle, lungs, left atrium, left ventricle
Deoxygenated blood from the upper body enters the heart through the _______________ vena cava
Superior
Sorry, I can't add the diagrams...
That's totally fine Kara! (Btw, you're so cool!! 😎 Thanks for making this quizlet!!)
Forming clots
platelets
Why/how does air move into the lungs during respiration?
The air flows from an area of higher concentration to an area of lower concentration inside the lungs.
What controls the breathing process?
The nerve cells in the part of the brain, called the respiratory center.
To regulate the body's breathing rate, the brain is respiratory center monitors
The pH of the blood
Why does a trip through the systemic portion of the circulatory system take longer for a red blood cell to complete than a trip through the pulmonary portion???
The trip through the systemic portion covers a longer distance
Which of the following correctly traces the passage of air through the respiratory system when entering the lungs?
Trachea, bronchus, bronchiole, alveolus
Gas exchange in the lungs happens as oxygen and carbon dioxide diffuse from regions of high to low concentration
True
Gas is exchanged between air and the blood in capillaries that surround the alveoli
True
Leukocytes rid the circulatory system antigens
True
Low pressure in the lungs is created by contracting the diaphragm and muscles between the ribs
True
The nasal cavity warms, moisturizes, and filters air before it passes into the rest of the respiratory system
True
Thrombocytes
platelets
Each sequence of relaxation and contraction of the heart is called a(n) _______________
cardiac cycle
Which organ system does the respiratory system rely on for transporting oxygen to the rest of the body?
circulatory
holding hemoglobin
erythrocytes
Which component of the blood increases in volume when a person is sick?
leukocytes
produced by the lymphatic system
leukocytes
In addition to blood cells, list at least 4 things that blood transports throughout the body
•waste •nutrients •hormones •carbon dioxide
Sorry for any typos...
😂 lol it's all good!
