The heart has four valves:
1. Tricuspid
2. Pulmonary
3. Mitral
4. Aortic
These valves ensure blood flows in one direction, preventing backflow and maintaining efficient circulation.
The heart has its own electrical system and can keep beating even outside the body — as long as it has oxygen.
That means the heart doesn’t need the brain to tell it to beat — it has its own pacemaker cells that generate electrical impulses all by themselves!

The heart has its own electrical system, and the cardiac plexus plays a role in regulating heart function. The cardiac plexus is a network of nerve fibers that innervate the heart, influencing heart rate and contraction strength.
The nerves that regulate heart rate are part of the autonomic nervous system.
1. Sympathetic nervous system: Increases heart rate and contraction force.
2. Parasympathetic nervous system: Decreases heart rate. The key nerve involved is the Vagus nerve.
The heart's electrical system includes the sinoatrial (SA) node, atrioventricular (AV) node, and other structures that allow it to beat without direct brain control. The SA node acts as the heart's natural pacemaker, generating electrical impulses that trigger contractions.
Your heart beats about 100,000 times a day — that’s over 35 million times a year!
And it keeps going non-stop, even while you sleep. It’s like having a tireless drum playing your life’s rhythm every single second.
Your heart creates enough pressure when it pumps that it could squirt blood up to 30 feet!
That's how powerful each heartbeat is — even though it seems like a soft "thump," it's strong enough to push blood through 60,000 miles of blood vessels in your body.
The heart has four valves:
1. Tricuspid
2. Pulmonary
3. Mitral
4. Aortic
These valves ensure blood flows in one direction, preventing backflow and maintaining efficient circulation.
3. Mitral Valve (Bicuspid Valve): Allows blood to flow from the left atrium to the left ventricle.
4. Aortic Valve: Allows blood to flow from the left ventricle to the aorta, the main artery that supplies blood to the body.

4. Aortic
These valves ensure blood flows in one direction, preventing backflow and maintaining efficient circulation.
1. Tricuspid Valve: Allows blood to flow from the right atrium to the right ventricle.
2.Pulmonary Valve: Allows blood to flow from the right ventricle to the lungs.
Spinach is a sneaky muscle booster! This leafy green is packed with nitrates, which can improve blood flow and muscle efficiency, giving you a natural edge in workouts—Popeye was onto something!😂
Your brain actually shrinks slightly when you're dehydrated—even mild dehydration (as little as 2%) can affect attention, memory, and mood.
HEALTH TIP:
Drink enough water throughout the day—aim for 6–8 glasses—to keep your brain performing at its best!
Everyone has a unique brain "fingerprint"! Just like fingerprints, no two brains have the same pattern of neural connections. This uniqueness is thought to be linked to individual differences in personality, behavior, and abilities. Pretty cool, right?
Dancing Keeps Your Brain Young: Busting a move doesn’t just burn calories—it can improve memory! Dancing activates the hippocampus, the brain area tied to learning and recall. Try a 5-minute dance session to your favorite tune for a brain and mood lift.
Your brain uses about 20% of your body's energy expenditure, despite accounting for only about 2% of its mass. That's why thinking hard can make you feel hungry! Your brain is a powerful energy consumer.
Nurse: How are you doing today and hope you are not experiencing any symptoms?
Patient: Yes Nurse I’m totally fine.
Nurse: Chakam📸..Before you start listing different symptoms for doctors during ward round😂😂😂
