The food then travels into the oesophagus. Your oesophagus is located near your trachea (windpipe). The epiglottis separates the nasal cavity and the lower airway from the passage of food whilst swallowing. The contractions of the muscles in your oesophagus push the food down your oesophagus and into your stomach. Your stomach is a hollow organ that holds food whilst it is being broken down by the enzymes.
If their skin is moist and coated with mucus, diffusion will occur. To get oxygen into its body it defuses into the worm; almost like the oxygen is being pulled into it. From there blood vessels grab the oxygen gas while being circulated by the pumping of its hearts. Soon after, the oxygen is used up and becomes carbon dioxide gas. The gas then defuses, or gets pushed, out of the worm; making room for more
The urinary bladder is a sac-like hollow organ that is used for the storage of urine. Urine slowly fills up the bladder and stretches its elastic walls and can hold 600 to 800 milliliters of urine. The urethra is the tube that transports urine from the bladder to the exterior of the body. There are two muscles in the urethra that control the flow of the urine. They are the internal sphincter which when open results in the sensation of needing to urinate and the external urethral sphincter a skeletal muscle that will allow urine to pass through or delay urination.
Your pulse and blood pressure go up, and you will start to breathe more rapidly. Your lungs open wide so they can take in as much oxygen as possible. This extra oxygen is sent to the brain which increases alertness. Your senses become sharper and epinephrine triggers the release of blood sugar and fats from storage sites in your body. The parasympathetic nervous system promotes the “rest and digest” response that calms the body down after the initial stress has passed.
The body cavity fills with gases as the bacteria decomposes tissue in the intestines. These gasses include carbon dioxide, methane, nitrogen, and hydrogen sulfide. At the same time decomposing tissues may begin to liquefy. The pressure of the gasses on the liquefying organs can cause the liquid to be forced to escape via the nose, mouth, and other orifices. The building gases also help to transport the pigmented sulfhemoglobin throughout the body giving the corpse a distinctive, marbled effect.
Well, breathing is important to the body in the sense that you can expel carbon dioxide from your lungs. Cells in our body use oxygen as well and not a good enough oxygen supply to the cells can lead to the death of cells. “Proper breathing, “ for example, the 4-7-8 breathing technique can help calm the mind and body. The technique can also supplies a good amount of oxygen to the body and help reduce stress, anxiety, and help to get better sleep. How does stress affect our breathing?
Introduction Metabolism is the sum of all anabolic and catabolic reactions within a living organism to sustain life. The energy required to perform these reactions is provided by oxygen in the form of ATP, therefore the oxygen consumption rate can be measured to determine the metabolic rate. Since oxygen is obtained through respiration, the efficiency of an organism’s respiratory system affects its metabolism. Previous studies have shown that caffeine affects the human respiratory center and occasionally dilates bronchus. It can thus stimulate human respiration and increase the metabolic rate (Haggins et al, 1915).
The bronchi and bronchioles are where air passes through either the nose or mouth, and toward the alveoli in the lungs. The airway splits into left and right braches. It splits down further and further until it reaches the terminal bronchioles. The bronchi have a very similar structure to the trachea. They both have c-shaped cartilage.
When larger substances, such as disease vectors or foreign bodies that are laden with pathogens, try to get into the respiratory tract, the hairs in the nose prevent the much larger substances from advancing far into the respiratory tract. Smaller substances that can bypass the air in the nose are trapped by mucus lining the epithelium of the respiratory tract. After this, the trapped foreign bodies and pathogens are forced up the respiratory tract into the pharynx and then swallowed into the alimentary
It feels like you’re slowly suffocating while moving up but when you go up you require more air. The lack of air isn’t good on the brain either. WIth your body taking most of the air it doesn’t allow your brain to get enough air which doesn’t allow you to think properly. Things you would’ve never done while having oxygen is harder to realise with a lack of oxygen. People would walk off the mountain, sat down too long, kept going too long
