The amount of air exchanged at rest is called Tidal volume
Lung volumes or respiratory volumes is the volume of gas in the lungs during a respiratory cycle. there are four types of respiratory volumes tidal volume, inspiratory reserve, expiratory reserve and residual volume.
The tidal volume is the total amount of the air that moves in or out of the lungs with each respiratory cycle in normal condition. It is around 500mL. It is an important clinical parameter for proper ventilation to take place.
Inspiratory reserve volume is a supplementary volume which could be effectively inhaled after the inspiration of a standard tidal volume. It is about 2500- 3100 ml.
Expiratory reserve volume is the additional capacity of air which can be forcibly expelled exhaled after normal expiration. It is around 1200 ml.
Residual volume is the volume of air residing in lungs after expiration. It is around 1100- 1200 mL.

Which epithelium is best suited for resisting abrasion and preventing pathogen entry into deeper tissues?
Epithelial cells best suited for resisting abrasion and preventing pathogen entry into deeper tissues are stratified squamous epithelial cells.
Stratified cells are layered cells, squamous cells are flat and epithelial cells are covering cells. Therefore, stratified squamous epithelial cells are flattened, layered covering cells arranged on a basement membrane.
Stratified squamous epithelial cells have very little to no intercellular spaces which prevent pathogen from passing through and entering into the deeper tissues. They are well suited for resisting abrasion because the uppermost layers are subsequently sloughed off and replaced before the basement membrane is exposed. These types of cells form the outermost layer of the skin.

Intensity of a stimulus, such as the intensity of noise that a person experiences, can be communicated through ______.
The intensity of a stimulus, such as the intensity of noise that a person experiences, can be communicated through the number of neurons that fire action.
A stimulus is a change detected by the neurons in a body for which a response is produced. The sensory nerves sense a stimulus and send signals to the brain. The brain interprets this message and sends a response action signal through the motor neurons.
The intensity of a stimulus is detected by the impulse of action potential carried by the sensory neurons. The number of sensory neurons will increase if an intense stimulus, which will lead to the generation of an increased action potential. The brain will determine the intensity of the increased action potential and send a response action from the motor neurons to act accordingly.

According to the endosymbiotic theory, it is simple for a big host cell and ingested bacteria to become dependent on one another for survival and develop a long-term bond. Due to their increased specialization through millions of years of evolution, mitochondria and chloroplasts can no longer survive outside of cells. Chloroplasts and mitochondria are remarkably similar to bacterial cells. They have unique DNA that is distinct from the DNA found in the cell's nucleus. Additionally, these organelles synthesize numerous proteins and enzymes necessary for their functions using DNA. Both mitochondria and chloroplasts are surrounded by a double membrane, which is additional proof that each was ingested by a primitive host.

What is the difference between the visceral and parietal layers of pleura and peritoneum?
Answer:
The difference between the visceral and parietal layers of pleura and peritoneum is:
Explanation:
The main differentiation between both visceral as well as parietal is that the former forms one of the 2 layers of the serosa that covers the organs, whilst the latter forms the second layer which lines the body cavity's walls. As a result, structures connected to organs are referred to as visceral, whereas those attached to the wall of most of the body cavity are called parietal.
The anatomical phrases visceral as well as parietal are used to characterise the serous membrane's components and structures. The walls of the whole organs in the thoracic as well as abdominopelvic cavities are often covered by a thin membrane called the serosa.
Aside from that, the pericardium, pleura, as well as peritoneum are indeed the serous membranes connected to the 3 serous chambers in the human body.

How are bacteria, archaea, fungi, protozoa, algae, and viruses distinguished on the basis of structure?
Bacteria, archaea, fungi, protozoa, algae, and viruses are distinguished on the basis of a structure by the three-domain system.
Three-domain system is a classification system in which cellular life is classified into three types which are archaea, bacteria, and eukarya domain.
Archaea are organisms that are made up of cells that lack a nucleus and other membrane-bound organelles which means that they are prokaryotic.
The domain bacteria differs from archaea in the composition of the cell wall and cell membrane in that the cell wall of bacteria consists of peptidoglycan while the cell walls of archaea do not consist of peptidoglycan. The lipids in the membrane of archaea are enclosed with hydrocarbons, unlike the bacteria in which lipids are enclosed with fatty acids.
Fungi and algae are included in the domain eukarya since they consist of a membrane-bound nucleus and hence are eukaryotic. Fungi and algae differ in cell structure in that the cells of algae have a single nucleus while the cells of fungi are multinucleated.
Viruses are not considered a part of any of the domains since viruses are not made of cells and they don't have the capability to perform any metabolic function. They remain inactive outside the host cell.

The factors of systemic blood pressure are,
-Heart rate
-Stroke volume
-Cardiac output
-Systemic vascular resistance
What causes systemic blood pressure?
Constriction of the tiny arteries is typically what raises systemic (or body) blood pressure (arterioles). As a result, the peripheral resistance to blood flow rises, increasing the stress on the heart and elevating arterial pressure. Both the greatest (Systolic) and lowest (Diastolic) points of blood pressure are recorded.
In most cases, systemic hypertension goes unnoticed. The disease is sometimes referred to as the silent killer because of this. You can only detect hypertension if you have your blood pressure monitored.
