Sound is a means of communication by animals. Many fishes are capable of producing sounds with the help of specialized structures. Fish have evolved the largest diversity of sound-producing mechanisms among vertebrates, and sounds are emitted in numerous contexts: e.g. disturbance situations, during courtship, competitive feeding and territorial encounters. Sounds are also produced unintentionally including those made as a by-product of feeding or swimming. The majority of sounds produced by…

1. Differentiate between skin of fish and amphibia Fish (Scoliodon) Amphibia (Frog) *Skin is rough and tough which remains *Skin is smooth and loose which remain attached with the underlying muscles. separates from the underlying muscles by lymph . sac.…

Hyperbaric Oxygen Therapy assists in wound healing by stimulating the blood vessels to dissolve more oxygen throughout the body from the increased administration of oxygen pressure. During this process, bacteria decreases, stem cells and growth factors increases, which promotes rapid wound healing. Side Effect Definition/Describe A. Pneumothorax: Pneumothorax is defined as a collapsed lung due to the presence of gas or air…

Without exercise, being inactive can lead to diseases such as coronary heart disease, osteoporosis, and colon cancer, according to Harvard researchers. Coronary heart disease, or Atherosclerosis, is a disease in which plaque, a waxy substance, is built up in the coronary arteries. Plaque can harden or break open after a while. Hardened plaque partially blocks the arteries and reduces the flow of oxygen-rich blood to the heart. Ruptured plaque can lead to blood clots which can completely block…

Goy, David The Functions of Blood Blood plays a very important role in maintaining the normal functions of the different, tissues, organs and organ systems in the body. It serves as the primary medium for carrying and transporting important gases, minerals and nutrients needed to maintain homeostasis. Blood is composed of several components: plasma, red blood cells, white blood cells and platelets. Plasma is the fluid compartment of the blood; it carries ions, minerals, nutrients, gases,…

Drowning is known dying due to submersion and inhaling water. Most drownings occur within males and children. Most people drown due to not knowing how to swim, Alcohol use while swimming , and/or no supervision while swimming. One thing most people do not pay attention to is how drowning in fresh water can be different from drowning in salt water. More drownings occur in fresh water then they do in salt water and in some case the victims can die hours after the incident. Water goes into the…

Background information Structure of the large intestine The large intestine (also known as large bowel or colon) is the last part of the gastrointestinal (GI) tract. It extends from the cecum to the anus, with the ascending colon, the transverse colon, the descending colon, the sigmoid colon and the rectum in between. The large intestine consists of four layers of tissue: the mucosa, submucosa, muscle and serosa (figure 1). The mucosa is made out of an epithelial layer, with a layer of…

Blood transfusion is a process in which blood is injected from one healthy human being to a patient; whom might be losing too much blood or suffering from an illness that requires more blood. This medical procedure is crucial in saving numerous lives. The first successful human-to-human blood transfusion was performed by James Blundell in 1818, yet a large number of patients had died because of wrong blood transfusion operations. The great discovery of Karl Landsteiner’s classification of ABO…

affected along with the pulmonary and renal systems. Cardiovascular side effects depend upon the previous underlying cardiopulmonary status of each patient. Conditions pertaining to congestive heart failure (CHF) and chronic obstructive pulmonary disease (COPD) cause hyperinflation, which compresses the heart and lungs. There are studies that are shown in this paper including beneficial effects of positive pressure ventilation (PPV)…

cardiovascular that has multiple arrhythmias must be taken into heavy consideration. Pushing a patient too far can cause even greater damage. A person’s blood pressure is also determined before the start of the exercise test. This determines how hard the heart is working, if the patient’s blood pressure is too high, again the trainer will need to watch how hard they work the client because more damage could happen if they are worked too hard. Balance and flexibility test can be administered…
