Why are the cartilaginous rings incomplete posteriorly?
The trachea, commonly called the windpipe, is the opening adjacent to the esophagus opening, that leads to the lungs. The cartilage rings are incomplete to allow proper collapsing, so that food can go down the right pipe.
How does the rib cage protect the Respiratory System?
Your respiratory system is the system that brings oxygen onto your body and is mainly associated with the lungs and the windpipe bringing the air down from your mouth. Teh ribs are the bones of your chest that curve round your lungs. They form a cage around the lungs which stops the lungs being crushed. If your lung is pressed flat it cannot take in air. It needs to be inflated like a balloon. Without your ribs every time you came into contact with something it would push the air out of your lungs and wind you.
The trachea, also known as the windpipe, is responsible for carrying air to and from the lungs. It is lined with a mucous membrane that helps to trap any dust or particles in the air before it reaches the lungs, protecting the respiratory system. The trachea also contains C-shaped rings of cartilage which provide structure and prevent it from collapsing.
Alveoli are tiny air sacs in the lungs where oxygen is taken in from the air we breathe and carbon dioxide is released from the blood. They have thin walls that allow for gas exchange between the air and the blood stream, ensuring that oxygen is absorbed and carbon dioxide is expelled from the body during respiration. This process is essential for providing the body with the oxygen it needs for energy production.
You breathe in the complete mixture of all the gases in the air. Your body then extracts some of the oxygen for you to use and replaces it with carbon dioxide as a waste product. Then you breathe out the resulting mix, which has more carbon dioxide and less oxygen in it than what you breathed in.
Describe the function of your diaphragm and explain how inhaling and exhaling occurs?
Breathing is done by your diaphragm. When you breathe in, your diaphragm tightens (contracts) and moves downward so your lungs can expand. When you breathe out (exhale) your diaphragm relaxes (expands) and moves up into your chest.
Are the teeth an important part of the respiratory system?
Teeth are not directly involved in the respiratory system. They are part of the digestive system, as they aid in chewing food to make it easier to swallow and digest. However, a healthy mouth with intact teeth is important for overall health and well-being, which includes the respiratory system.
How does the respiratory system work with the other body systems?
The respiratory system works with the body to help our body function correctly. One of the things it does is it gives our cells/blood oxygen to take to the rest of our body.
the respiratory system affects the body by allowing you to obtain oxygen
What are the reactants and products of anaerobic respiration?
G: Glucose + 2 NAD+ + 2 ADP + 2 Pi → 2 NADH + 2 pyruvate + 2 ATP + 2 H2O + 2 H+
input = Glucose, NAD+, ATP => also (+) coenzyme A?
output = Pyruvate, NADH, net ATP => Acetyl CoA + CO2 + more NADH
Kreb's Cycle:
Input = Acetyl CoA, NADH, ATP
Output = CO2, ATP, NADH, FADH2
ETC:
Input = H+, O2, NADH, FADH2
Output = H2O and ATP, NAD+
Explain two ways in which anaerobic respiration in humans is different from aerobic respiration?
Anaerobic respiration takes place in the absence of oxygen and food substances are patially broken down.They releases smaller amount of energy and produces lactic acid or alcohal.In human body, anaerobic respiration often occurs in the muscles during vigorous exercise because they don't get enough oxygen.
Anaerobic respiration in humans can only happen for a short amount of time. The reason for this is that Anaerobic means without oxygen, and humans need oxygen to breath. Aerobic means with oxygen, so normally humans aerobically respire. However, if you are short of breath after viscous exercise for a short period of time you anaerobically respire.
How does aerobic respiration happen?
To produce the maximum amount of ATP (energy) your body can. Its either anaerobic (no oxygen) or aerobic respiration. Anaerobic respiration produces less ATP than aerobic due to lack of oxygen, thus the citric acid cycle and the electron transport chain can not continue as oxygen is needed.
When does anaerobic respiration take place?
During the age of the dinosaurs,on the one hundred and third full moon the Anteater had crashed to earth, five ninjas teleported into its anal passages and drank the milk that they discovered there. The milk gave them a stomach ache, but they enjoyed and welcomed the feeling.
What causes heart rate to increase during a fight or flight response?
During a fight or flight response, the release of stress hormones like adrenaline (epinephrine) triggers an increase in heart rate. This physiological response is designed to prepare the body for immediate action by supplying more oxygen and nutrients to the muscles and brain.
Cilia are hair-like structures found on the surface of cells. They help in movement by either propelling fluid or particles past the cell, or by moving the cell itself. In the respiratory tract, cilia help to sweep mucus and debris out of the airways.
Surface tension is a property of a liquid that causes its surface to behave like an elastic membrane. It is due to the cohesive forces between the liquid molecules which results in the liquid trying to minimize its surface area. This leads to effects like droplets forming or insects being able to walk on water.
What does Cappilarisation of the Alveoli mean?
Cappilarisation is where the capillaries in the lungs and surrounding the alveoli increase in numbers, making gaseous exchange in the lungs more efficient so that the respiratory system is more efficient gnereally and during exercise, meaning the heart does not have to work at a higher level to supply nutrients and oxygen to muscles and organs.
What happens to the body during the bleep test?
During the bleep test, which is also known as the shuttle run test, the body experiences an increase in heart rate, breathing rate, and oxygen consumption as the intensity of the exercise gradually increases. Muscles are engaged to run back and forth between markers, leading to fatigue as the test progresses. The body works to adapt to the increasing demand for energy production until exhaustion or the test is completed.
Can you talk and breathe at the same time?
YES. but you know that you cannot keep your eyes open while you sneeze - fact. You normally are breathing out when you are talking. It's the outbound air flow that vibrates your vocal cords and produces the fundamental sounds that become speech. You can do this breathing in but it's hard.
You put more efforts when you exhale air or when you inhale the air?
During normal breathing at rest, inspiration is an active process while expiration is passive. So under normal conditions, you put more energy into inspiration than expiration.
Which structure contributes to pressure changes in the chest cavity?
when you inhale..(take in oxygen)..the air fills up the lungs, the ribcage expands and the muscle sheet called the diaphragm pushes downward and flattens as you inhale ..whn you ehale the muscle returns back to domed-shape
Where does aerobic respiration occur?
Aerobic metabolism takes place in the mitochondria where oxygen is used to accept the electrons freed in the process of metabolism:
C6H12O6 (aq) + 602 (g) → 6CO2 (g) + 6H2O (l) + 2880KJ
What is the byproduct of respiration?
False
Co2...carbon dioxide
(dont read this if u dont want to)
there are different forms of respiration,
aerobic respiration= oxygen + glucose -> carbon dioxide+ water (+energy)
anaerobic respiration=
What is olfactory functions of the nose?
The olfactory functions of the nose involve the detection and processing of odors. The olfactory receptors in the nose can detect various molecules in the air, which are then translated into different smells by the brain. This sense of smell plays a crucial role in our ability to taste food, detect dangers, and experience emotions.
