Guiding Question: How do the circulatory and respiratory systems work together to keep the body in homeostasis?

Do Now: How does our body maintain homeostasis when we

exercise?

A #2 Respiratory

B #3 Respiratory3. Which structures are correctly paired with

their primary function?(1) A and G—transmission of nerve impulses(2) B and E—photosynthesis(3) C and H—digestion of food(4) D and F—gas exchange

C #3 Respiratory

Smoking may damage the respiratory system because deposits from the smoke can

(1) interfere with ciliary action in the trachea(2) trigger the release of antigens by the alveoli(3) block the transmission of impulses that

regulate breathing(4) lower blood pressure in the mucous

membranes of the bronchioles

A #4 Respiratory

Humans require multiple systems for various life functions. One vital system is the respiratory system. Identify two structures that are part of that system, and state how each structure you identified functions as part of the system.

B #4 Respiratory

Describe one example of diffusion in the human body. In your description be sure to:

• * identify the place where diffusion takes place

• * identify a substance that diffuses there• * identify where that substance diffuses from

and where it diffuses to, at that place

C #4 Respiratory

Using one or more complete sentences, state one specific change that occurs in the gas composition of the blood as the blood moves from the lungs to the heart. Specify whether the change is an increase or a decrease in composition.

A #1 Circulatory

Blood normally flows from the capillaries directly into

(1) small arteries (3) lymph vessels(2) small veins (4) heart atria

B #1 CirculatoryThe life function of transport in an organism

directly involves those activities used to(1) absorb and distribute materials(2) obtain and hydrolyze materials(3) release energy from food(4) produce cellular waste products

C #1 Circulatory

Which statement best describes arteries?(1) They have thick walls and transport blood

away from the heart.(2) They have thick walls and transport blood

toward the heart.(3) They have thin walls and transport blood away

from the heart.(4) They have thin walls and transport blood

toward the heart.

A #2 Circulatory

Which body structures have walls one cell thick?(1) veins and arteries(2) trachea and bronchi(3) capillaries and alveoli(4) lymph vessels and stomach

B #2 CirculatoryWhat is a major difference between red blood cells

and white blood cells?(1) Red blood cells contain hemoglobin, but white

blood cells do not.(2) Red blood cells can move, but white blood cells

cannot.(3) Red blood cells contain nuclei, but white blood

cells do not.(4) Red blood cells engulf foreign bacteria, but white

blood cells do not.

C #2 Circulatory

During a race, the body temperature of a runner increases. The runner responds by perspiring, which lowers body temperature. This process is an example of

(1) maintainence of homeostasis(2) an anitgen-antibody reaction(3) an acquired characteristic(4) environmental factors affecting phenotype

through the body. Which structure carries oxygenated blood to the body?

(1) structure 1(2) structure 2(3) structure 7(4) structure 8

B #3 CirculatoryThe diagram represents several major

circulatory pathways in the human body. Which sequence represents the normal blood flow in circulation to the lungs?

(1) 2 → 5 → 7 → 4(2) 4 → 8 → 1 → 6(3) 1 → 6 → 2 → 5(4) 5 → 7 → 3 → 8

C #3 CirculatoryThe diagram represents the pathway of blood

through the body. Which structure represents the chamber of the heart that receives oxygenated blood directly from the lungs?

(1) structure 5(2) structure 6(3) structure 3(4) structure 4

A #4 CirculatoryDescribe one example of diffusion in the human

body. In your description be sure to:* identify the place where diffusion takes place* identify a substance that diffuses there* identify where that substance diffuses from

and where it diffuses to, at that place

B #4 Circulatory

Humans require multiple systems for various life functions. One vital system is the circulatory system. Identify two structures that are part of that system, and state how each structure you identified functions as part of the system.

C #4 Circulatory

Organ systems of the human body interact to maintain a balanced internal environment. As blood flows through certain organs of the body, the composition of the blood changes because of interactions with those organs. State one change in the composition of the blood as it flows through the circulatory system.

A #1 The Cell

The main result of aerobic respiration is the(1) conversion of radiant energy into chemical

energy(2) production of lactic acid as an end product(3) storage of energy in a polysaccharide(4) production of ATP from the breakdown of

glucose

B #1 The Cell
