Respiratory System

Hydra is a multicellular animal with tissue level of organization but has no organs. It has a large surface area in relation to its volume. Being diploblastic, it has two layers of cells in its body. As most of its cells are in direct contact with water, the ectodermal cells exchange gases with external water while endodermal cells with water that comes within the gastro-vascular cavity.

The RESPIRATORY SYSTEM is how you breath, so your; trachea, lungs, alveoli etc hope this helped!

When lying down at night, your cough can get worse. There are three reasons for a cough getting worse at night. The first reason is gravity, the second reason is the dry indoor environment, and the third reason is the human body naturally getting rid of congestion.

When you breath the first step is when the air enters your nose, then as it passes through your nose it is warmed by the tiny hairs and blood vessels there and any dust and/or foreign articles are caught by mucus and those tiny hairs, then the air goes through the pharynx and larynx and as it passes through them it gets warmer and clearer by the same method in the nose, it finally reaches the trachea, and then divides when the trachea becomes two bronchi which then branch again and again until it reaches the little sacs called alveoli and the air fills them up, oxygen and co2 exchange happens then, by means of capillaries that pass around these sacs, the capillaries give the alveoli co2 and take the oxygen, then the co2 goes back where the oxygen had come from, so the lungs are empty and need another dose of air, so it happens all over again and so on.

Air passes down the throat and into the trachea. Soon the air reaches a place where the trachea branches into two tubes. Each of these called bronchus.

you give your lungs less time to absorb the oxygen in the air because you breath it out immediately.

yes

The teleopgical explanation tries to see beneficial purpose in a given phenomenon.

This jerky inspiratory effort asscoiated with closure of glottis, is opposite of jerky expiratory effort such as sneeze or cough, which are aimed at throwing out foreign material from the lungs.

The hiccups therefore appear to be efforts to jerkily bring in outside air, apparently to prevent possible collapse, as a result of the signal for the hiccup, which apears to be anything that mimicks the sudden collapse.

So it appears that, any stimulation of vagus or phrenic nerves or diaphragm itself; due to any pathology, when appears akin to beginning of the process of sudden collapse, the hiccups are generated.

Experiemntal verification may be done by simulating impending collapse of various degrees and seeing the response of body.

Hemostasis

Depends if it is a wild or tamed bear, the kind of bear and the time of the year as well as the climate zone

breathing issues, because the body cannot release caarbon dioxide

and also being tired alot not able to get up

it means your dying so hahahaha if u have grey lungs

Tidal Volume x Respiratory Rate

If there is metabolic alkalosis (high pH in the blood) or metabolic acidosis (low pH in the blood), the respiratory system will compensate by either increasing or decreasing the rate of respiration (expulsion or retention of CO2 to bring the blood pH back to within normal limits).

Because we have too many class-B telephone cleaners. And if you flunk out of that course, be alert... The world needs more lerts.

respiratory and cardiovascular systems

The function of the respiratory system is to take in oxygen and to exhale gases such as carbon dioxide.

If the respiratory system isn't working well - such as in asthma, bronchitis, emphysema, sarcoidosis - the amount of oxygen in the blood will fall and the poisonous gases will not be exhaled properly. All body systems need oxygen to function properly so when there is too little oxygen, the body shuts down 'non-essential' tasks so that what little oxygen there is can be diverted to 'essential' functions such as the brain. This explains why people who are short of breath are so tired and find everything a huge effort - there just isn't the oxygen available to help them do non-essential tasks.
