An overview of the respiratory system of the human body

The role of muscles The respiratory muscles displace the equilibrium of elastic forces in the lung and chest in one direction or the other by adding muscular contraction.

Additionally, along these vessels there are small bean-shaped lymph nodes that serve as filters of the lymphatic fluid. They are soluble proteins secreted by the plasma offspring clones of primed B cells. They also encourage polys to adhere to the walls of capillaries margination from which they can squeeze through in a matter of minutes to arrive at a damaged area.

The blood of someone of type AB, has both antigens, hence has neither antibody. Sticky mucus in respiratory and gastrointestinal tracts traps many microorganisms.

The flow of air is rapid or slow in proportion to the magnitude of the pressure difference. The right lymph duct drains the right sides of the thorax, neck, and head, whereas the thoracic duct drains the rest of the body.

Lung diseases affecting the alveoli include: The accumulated mucus results in repeated lung infections. Nervous system— brain, spinal cord, nerves Control system of the body, responds to internal and external changes, activates muscles and glands.

Any subsequent immune response to an antigen is called a secondary response and it has a shorter lag time, a higher overall level of response, a more specific or better "fit" to the invading antigen, utilizes IgG instead of the large multipurpose antibody IgM. Videos are a great way for them to learn about different body systems and organs.

Other signals such as galanin-like peptide GALP and NPW also modulate appetite, possibly by modifying orexin and melanin-concentrating hormone MCHillustrating the high complexity of ghrelin-associated feeding networks.

Type A blood has A antigens and type B blood has B antigens. Milk yield is greatly reduced to zero in lactating animals.

CD stands for cluster of differentiation and there are more than one hundred and sixty clusters, each of which is a different chemical molecule that coats the surface. A form of COPD characterized by a chronic productive cough.

It flows in the lymphatic vessels and bathes tissues and organs in its protective covering. Aspiration pneumonia in cattle after treatment for milk fever is usually fatal.

Lung Diseases Overview

The stomach is a formidable obstacle insofar as its mucosa secrete hydrochloric acid 0. Nevertheless, cells can bind to receptors whose fit is less than optimal when required. All of these of these mechanisms hinge on the attachment of antigen and cell receptors. Critical intermediaries are NPY and AGRP neurons, in which ghrelin stimulates mitochondrial respiration by inducing uncoupling-protein Areas of the skin not covered with hair, such as the palms and soles of the feet, are most susceptible to fungal infections.

B cells and T cells. Thoracic auscultation reveals reduced lung sounds over affected consolidated lung, with increased breath sounds over normal lung. T cells are nonantibody-producing lymphocytes which are also produced in the bone marrow but sensitized in the thymus and constitute the basis of cell-mediated immunity.

The urogenitary tract is lightly colonized by various bacteria and diphtheroids. Dendritic cells are covered with a maze of membranous processes that look like nerve cell dendrites. Each small increment of expansion transiently increases the space enclosing lung air.

This tendency of the lung to collapse or pull away from the chest can be measured by carefully placing a blunt needle between the outside of the lung and the inside of the chest wall, thereby allowing the lung to separate from the chest at this particular spot.

Animals that survive develop chronic abscesses and fibrous adhesions between the visceral and parietal pleura.

Body Systems

Lymphatic system— red bone marrow, thymus, lymphatic vessels, thoracic duct, spleen, lymph nodes Houses white blood cells lymphocytes involved in immunity. Poor function in the nerves controlling the respiratory muscles causes difficulty breathing. A transtracheal wash can help identify the causative agent for which an antibiotic sensitivity can be obtained.

It explains the difference between voluntary and involuntary muscles, as well as the three types of muscles. A phagocyte is a cell that attracts by chemotaxisadheres to, engulfs, and ingests foreign bodies.

Vaccines for cholera have a relatively poor fit so they do not protect against all forms of the disease and protect for less than a year. In general, senescence impairs appetitive effects of key neuropeptides.

This can cause shortness of breath and chest pain. All cells are coated with various substances. The lung—chest system The forces that normally cause changes in volume of the chest and lungs stem not only from muscle contraction but from the elastic properties of both the lung and the chest.A collection of human body videos for kids on YouTube.

A Visual Introduction to Human Anatomy

Human anatomy is the study of the systems of the body which is made up of cells, tissues, and organs. In order for blood to provide oxygen to the body, the body must have a way of obtaining that oxygen. The respiratory system allows air to enter the lungs and for oxygen to diffuse into the blood.

*The human body consists of several major body systems: Circulatory System, Digestive System, Endocrine System, Excretory System, Immune System, Muscular System, Nervous System, Reproductive System, Respiratory System, Skeletal System All of the body systems work together to maintain a healthy body.
