What human activity would most likely decrease the amount of carbon in the atmosphere

At list of processes associated with CO2 transport in the blood. Classify each process as occurring predominantly at peripheral

nataly862011 [7]

Answer:

a. CO2 is produced ---> occurs predominantly at the peripheral tissues

b. CO2 + H20 to form H2CO3 ---> occurs predominantly at the peripheral tissues

c. Bicarbonate combines with H+ to form H2CO3 ---> occurs predominantly in the lungs

d. CO2 diffuses into blood ---> occurs predominantly at the peripheral tissues

Explanation:

Peripheral gas exchange or internal respiration is the gaseous exchange that occurs between the blood and the tissues of the body across the walls of the peripheral capillaries in contrast to external respiration which is the exchange of respiratory gase, carbon (iv) oxide and oxygen, between the body and the external environment occuring at the lungs.

During respiration, carbon dioxide is removed from the body through the lungs while oxygen is taken into through the lungs.

Carbon dioxide is produced as a waste product of metabolism by the tissues of the body. Removal of carbon dioxide is of utmost importance and occurs in three distinct ways in the body:

1. First carbon dioxide is transported in dissolved form in the blood to the lungs.

2. Carbon dioxide combines reversibly with hemoglobin to form carbaminohemoglobin and is transported to the lungs where it dissociates from hemoglobin is removed via expiration

3. Carbon dioxide is transported in the form of bicarbonate in blood to the lungs where it removed by the following process : i) carbon dioxide produced in the peripheral tissues diffusers into the and into the red blood cells. (ii) The enzyme carbonic anhydrase converts it to carbonic acid (iii) Carbonic acid dissociates into bicarbonate and hydrogen ions. Hydrogen ions binds to haemoglobin while bicarbonate is exchange with chloride ion in the plasma. (iv) Bicarbonate is transported to the lungs in blood plasma. (v) At the lungs, bicarbonate renters the red blood cells in exchange for chloride ions. The bicarbonate combines with hydrogen ions released from hemoglobin to form carbonic acid. Carbonic acid is broken down to carbon dioxide and water by carbonic anhydrase in the red blood cells. Carbon dioxide diffusesout into the lungs and is expelled.

Therefore, the processes in the question above can be classified thus:

a. CO2 is produced ---> occurs predominantly at the peripheral tissues

b. CO2 H20 to form H2CO3 ---> occurs predominantly at the peripheral tissues

c. Bicarbonate combines with H+ to form H2CO3 ---> occurs predominantly in the lungs

d. CO2 diffuses into blood ---> occurs predominantly at the peripheral tissues

It should be near land because theyre deposited in shallow water

Match the following items. 1. insertion inner, light-sensitive layer of the eye 2. sympathetic system point where a muscle is at

Sergeu [11.5K]

Answer:

1. Inner, light-sensitive layer of the eye. Retina

2. Point where a muscle is attached to the more movable part. Insertion

3. Outer, fibrous layer of the eye. Sclera

4. Translates sound vibrations into nervous impulse. Cochlea

5. Prepares the body for activity. Sympathetic system

6. Sense of balance. Semicircular canals

7. Coordinates our muscular movements. Cerebellum

8. Point where the muscle is attached to the less movable bone. Origin

9. Active when the body is resting. Parasympathetic system

10. In the brain stem, controls the activity of internal organs. Medulla oblongata

Explanation:

The retina is the internal layer of the eye. It receives the light from the exterior and transforms these stimuli into nervous stimuli, which travels to the brain to give an image.

The sclera is the outer layer of the eye. It protects the eye and keeps the eye's shape.

A muscle has an origin and an insertion. The first one is the part attached to the less movable bone and the second one to the more movable part. These two parts can be in different bones. When the muscle contracts, the bone attached to the insertion moves towards the origin of the muscle.

The cochlea and the semicircular canals are in the inner ear. The cochlea is the organ responsible for transforming the sound's vibrations into nerve impulses that will travel to the brain so that we can hear. In its interior, there are cells that have hairs, which move with the vibrations and transmit this message to the nervous system.

The semicircular canals are three and with liquid that moves as we move. The movement of this liquid moves hair cells that are in the canals. These hair cells inform our brain about our location in space and give us a sense of valance.

The cerebellum is part of the central nervous system. It involves the coordination of movements, learning new movements, and controlling them.

The sympathetic and parasympathetic nervous systems are part of the autonomic nervous system. The first one prepares our body for an emergency or an activity. It is the one that increases our respiratory frequency, our heart rate, dilates our pupils, makes us more alert, amongst other things. On the other hand, the parasympathetic system relaxes our body, slowing our heart rate, is involved in the digestion and the relaxation of our muscles. It activates, for example, after we eat.

The medulla oblongata is part of the brainstem. It controls involuntary actions such as heart rate, respiration, and vasoconstriction. As it controls these functions, it affects internal organs like the heart, lungs, arteries, etc.
