Why Adrenaline is Vital for Anaphylaxis: Understanding Adrenergic Receptors
Kia ora team,
In this video, we explore why adrenaline is the go-to treatment for anaphylaxis, a severe allergic reaction that can be life-threatening.
We will explore how adrenaline works, focusing on its interaction with adrenergic receptors in the body. We will discover the critical role these receptors play in reversing the symptoms of anaphylaxis, such as swelling, difficulty breathing, and low blood pressure.
Happy studying,
Ben

Kia ora team, Let's talk about the difference between a haemothorax, a pneumothorax and a tension pneumothorax and how they can be life-threatening. - Haemothorax is the accumulation of blood in the pleural space. Significant blood loss into the pleural space can collapse the lung and cause hypoxia, and lead to hypovolemic shock, decreasing blood pressure and reducing perfusion to vital organs....

Kia ora team. Let’s talk about how beta-2 agonists help the treatment of asthma symptoms. Asthma is a chronic inflammatory condition that narrows the airways, making breathing difficult. Beta-2 agonists work by relaxing the smooth muscles around the airways, leading to bronchodilation. They also stabilise mast cells to stop degranulation and stop the release of inflammatory mediators. This decr...

Kia ora team, Let's discuss how the sympathetic nervous system responds to hypotension. The receptors in the sympathetic nervous system, the organs where they are found and the effects they cause to help increase blood pressure. How does the nervous system respond to hypotension? Alpha-1 Receptors (α1) • Locations: Smooth muscle cells of arterioles and venules • Actions: Vasoconstriction, incre...

Kia ora team. Let's look at how the body regulates blood glucose. Regulation of Blood Glucose The regulation of blood glucose levels is a complex process that involves multiple organs, hormones, and metabolic pathways. The pancreas, liver, and various cellular processes work together to maintain glucose homeostasis, ensuring that blood sugar levels remain within a healthy range. Key hormones su...

Fat burns in the flame of carbohydrate. Biochemistry of fat and carbohydrate metabolism. To fully breakdown fat you need to break down carbohydrates. Kia ora team, let's talk about how fats burn in a carbohydrate flame. Let's start with lipolysis, the process by which triglycerides, stored in fat cells, are broken down into free fatty acids and glycerol. These free fatty acids are then released...

Kia ora team, Let's discuss the pathophysiology of type 1 diabetes mellitus and diabetic ketoacidosis. Type 1 diabetes -A person is born with a genetic susceptibility to type 1 diabetes -They undergo a triggering event (eg. infection) -An autoimmune response causes the destruction of beta cells of the islets of Langerhan in the pancreas -Therefore they now lack the ability to create insulin (ty...

Kia ora team, Type 1 and Type 2 diabetes mellitus are both chronic conditions that affect the way the body regulates blood sugar (glucose), but they have distinct differences: - Type 1 Diabetes: - Cause: Type 1 diabetes has a strong genetic component. A triggering event occurs, such as an infection or trauma, and an autoimmune reaction results. This is where the body's immune system attacks and...
