Preeclampsia Pathophysiology and Schematic Diagram

Preeclampsia Pathophysiology and Schematic Diagram

One of the toxemias of pregnancy is preeclampsia which is characterized by an increased blood pressure, proteinuria and edema.It usually occurs in the late part of second trimester or during the third trimester but it may also appear during the first trimester in some women. Interestingly, many women who suffered preeclampsia have said that the...
Pulmonary Embolism Pathophysiology and Schematic Diagram

Pulmonary Embolism Pathophysiology and Schematic Diagram

Pulmonary embolism is most commonly due to a blood clot or thrombus. However, other types of emboli occur from air, fat, amniotic fluid and sepsis.  Normally, the heart pumps blood to the lungs for oxygenation. Then, oxygen-rich blood is now carried into the system via the arteries. Once oxygen is utilized in the body, it...
Pathophysiology of Diabetic Ketoacidosis

Pathophysiology of Diabetic Ketoacidosis

Diabetic Ketoacidosis is a serious complication of Diabetes Mellitus Type 1. The problem in Diabetes Mellitus Type 1 is the absolute lack of insulin. Without insulin, glucose will not be transported to the cells. Consequently, a person feels hungry despite of eating adequately and the level of glucose in the body is increasing because cell...
Acute Glomerulonephritis (AGN) Pathophysiology & Schematic Diagram

Acute Glomerulonephritis (AGN) Pathophysiology & Schematic Diagram

The kidney/s are the main organs of the urinary system. Its primary function is to filter the blood for waste products and excrete it out of the body through the urine. Another of its function is on the the regulation of blood pressure through maintaining rennin-angiotensin balance and helps in the formation of Red Blood...
Coronary Artery Disease Pathophysiology

Coronary Artery Disease Pathophysiology

Introduction Before the heart can pump blood to supply the body with oxygen and other nutrients, it has to supply its own needs first. And this is where the coronary arteries take in charge. They are responsible for supplying the oxygenation needs of the heart. The normal coronary blood flow is about 225 ml/min. What...
Asthma Pathophysiology and Schematic Diagram

Asthma Pathophysiology and Schematic Diagram

Asthma is a chronic inflammatory airway disorder characterized by airflow obstruction and airway hyperresonsiveness to multiple stimuli. Asthma despite common to children can occur at any age. However according to statistics, about 50% of the people suffering from asthma are ages 10 years and below. There are twice as many boys compared to girls with...
Acute Hemorrhagic Pancreatitis Pathophysiology

Acute Hemorrhagic Pancreatitis Pathophysiology

Acute hemorrhagic pancreatitis is characterized by inflammation of the pancreas. In the later part, vessels ruptured resulting to tissue ischemia. Eventually, it will lead to tissue necrosis. The main problem in acute hemorrhagic pancreatitis is autodigestion of the pancreas. The cause of inflammation mechanism in pancreatitis is unknown. Although it is considered as the milder...
Esophagitis Pathophysiology and Schematic Diagram

Esophagitis Pathophysiology and Schematic Diagram

Esophagitis is a health condition wherein there is an inflammation of the esophagus. This comes either acute or chronic. It affects a staggering 15% of pregnant women and 5% of obese persons. Gastroesophageal reflux is the most common cause of esophagitis. The backward flow of hydrochloric acid (HCl) and its duration of exposure against the...
Squamous Cell Cancer Pathophysiology and Schematic Diagram

Squamous Cell Cancer Pathophysiology and Schematic Diagram

What is Squamous Cell Cancer? The exact etiology of Squamous Cell Cancer is unknown. However medical textbooks point out different risk factors such as exposure to cancer-promoting stressors and the response of the body to those exposures combine to determine the risk of developing cutaneous SCC. Where squamous cell cancer usually located? Head and neck...
Concept of Carcinogenesis - The Start Where End Begins

Concept of Carcinogenesis – The Start Where End Begins

CANCER, medically termed as CA or cellular aberration is one of the major causes of sufferings and death around the globe. It is cause by a carcinogen and co-carcinogen (required for carcinogen to affect human cell), and this was initiated by wrong and faulty life­style. A combined of these two produces cancer cell called oncogene,...
Bleeding Esophageal Varices Pathopysiology & Schematic Diagram

Bleeding Esophageal Varices Pathopysiology & Schematic Diagram

Esophageal varices are dilated veins forming vesicles on the lower portion of the esophagus and stomach. These are highly sensitive to pressure like coughing and sneezing which leads to its easy rupture and bleeding. This causes other health problems like anemia from unrecognized and untreated mild bleeding. 95% of all cases of esophageal varices are...
Appendicitis Pathophysiology & Schematic Diagram

Appendicitis Pathophysiology & Schematic Diagram

The vermiform appendix is a tiny tubular organ that is close-ended on one end and the other is connected to the cecum. It is sometimes called the tail of the large intestine or colon. It is located below the junction between the small and large intestine (ileocecal valve). It has no known digestive function but...
