infarction, death of tissue resulting from a failure of blood supply, commonly due to obstruction of a blood vessel by a blood clot or narrowing of the blood-vessel channel. The dead tissue is called an infarct.

A) There are many possible causes of hemorrhage, including:
1. Alcohol, drug, or tobacco use that is heavy or long-term (bleeding in the brain).
2. Blood clotting disorders.
3. Cancer.
4. Complications from medical procedures, such as surgery or childbirth.
5. Damage to an internal organ.
6. Hereditary (inherited) disorders, such as hemophilia and hereditary hemorrhagic telangiectasia.
7. Injuries, such as cuts or puncture wounds, bone fractures,s or traumatic brain injury.
8. Violence, such as a gunshot or knife wound, or physical abuse.
9. Viruses that attack the blood vessels, such as viral hemorrhagic fever.
B) Depending on the location or cause, a hemorrhage might be called:
1. Bruise or hematoma (a particularly bad bruise). Both involve bleeding just under the skin.
2. Hemothorax, blood collecting between the chest wall and lungs.
3. Intracranial hemorrhage, bleeding in the brain.
4. Nosebleed.
5. Petechiae, tiny spots on the skin that may be purple, red, or brown.
6. Postpartum hemorrhage, more bleeding than normal after childbirth.
7. Subarachnoid hemorrhage, a type of stroke that can be caused by head trauma.
8. Subconjunctival hemorrhage, broken blood vessels in the eye.
9. Subdural hematoma, blood leaking into the dura mater, the membrane between the brain and skull.

Haemorrhage is bleeding from a damaged blood vessel. Many things can cause haemorrhage inside and outside the body. Some common causes of haemorrhage include alcohol, drug, or tobacco use that is heavy or long-term, blood clotting disorders, cancer, complications from medical procedures such as surgery or childbirth, damage to an internal organ, hemophilia, leukemia, liver disease, menorrhagia (heavy or prolonged menstrual bleeding), thrombocytopenia (low blood platelet count), von Willebrand disease, vitamin K deficiency, and brain trauma.

The following are the different types of Hemorrhage: ( There are two types of Hemorrhage: internal and external.)
A) Upper Head:
-Intracranial Hemorrhage: A bleeding that occurs in the skull.
-Cerebral Hemorrhage: This is one of the types of intracranial Hemorrhage where the brain tissue bleeds within itself.
-Intracerebral Hemorrhage: When the brain bleeds due to the rupture in the blood vessel within the head.
-Subarachnoid Hemorrhage (SAH): when there is blood present within the subarachnoid space due to a pathologic process. It is a nontraumatic type of hemarrhage, typically caused due to a berry aneurysm or arteriovenous malformation.
B) Eyes:
-Subconjunctival Hemorrhage: A broken blood vessel in the sclera – the white of the eyes – results in the blood eye. It often occurs due to strain, including sneezing, coughing, vomiting, or other kinds of strain.
C) Nose:
-Epistaxis: It is commonly known as a nosebleed.
D) Mouth:
-Tooth eruption: When you lose a tooth, it is known as a tooth eruption.
-Hematemesis: You start vomiting fresh blood.
-Hemoptysis: When you start coughing blood from the lungs is called hemoptysis.
E) Lungs:
-Pulmonary Hemorrhage
F) Gastrointestinal:
-Upper gastrointestinal bleed
-Lower gastrointestinal bleed
-Occult gastrointestinal bleed
G) Urinary Tract:
-Hematuria – When you urinate, there is blood. It is known as hematuria.
H) Gynacologic:
-Vaginal bleeding
-Postpartum Hemorrhage
-Breakthrough bleeding
-Ovarian bleeding: Patients with polycystic ovary syndrome undergoing transvaginal oocyte retrieval are more likely to experience ovarian bleeding. It is fatal and is a common complication of the procedure.
I) Anus:
-Melena – occurs when there is an upper gastrointestinal bleeding
-Hematochezia – occurs when there is lower gastrointestinal bleeding or brisk upper gastrointestinal bleeding
J) Vascular:
-Ruptured aneurysm
-Aortic transection
-Iatrogenic injury
Haemorrhage is blood escaping from the circulatory system from damaged blood vessels.

There are many types of edema:
Types include:
1. Peripheral edema: This affects the feet, ankles, legs, hands, and arms. Symptoms include swelling, puffiness, and difficulty moving certain parts of the body.
2. Pulmonary edema: This occurs when excess fluid collects in the lungs, making breathing difficult. This can result from congestive heart failure or acute lung injury. It is a serious condition, it can be a medical emergency, and it can lead to respiratory failure and death.
3. Cerebral edema: This occurs in the brain. It can happen for a range of reasons, many of which are potentially life threatening. Symptoms include:
headache
neck pain or stiffness
whole or partial vision loss
changes in consciousness or mental state
nausea
vomiting
dizziness
4. Macular edema: This is a serious complication of diabetic retinopathy. Swelling occurs in the macula, which is the part of the eye that enables detailed, central vision. The person may notice changes to their central vision and how they see colors.
5. Pitting edema: With this type, which can occur in peripheral edema, pressure applied to the skin leaves an indent or pit in the skin.
6. Periorbital edema: This refers to inflammation and puffiness around the eye or eyes. The puffiness is due to fluid buildup and is usually temporary.
Edema can occur in other locations as well, but those mentioned above are the most common.
See lessComplications of oedema may include difficulty in walking, stiffness, stretched skin which can become itchy and uncomfortable, increased risk of infection in the swollen area, decreased elasticity of arteries, veins, joints, and muscles, and increased risk of skin ulcers.

The 2 most important causes are: 1. Thrombosis. 2. Thromboembolism. Other (minor) causes include – 1. Vasospasm. 2. Compression of a vessel. 3. Torsion of a vessel by twisting around on itself. 4. Traumatic rupture. 5. Expansion of an atheroma.
