Van hai lá và van ba lá là van tim nằm giữa tâm nhĩ và tâm thất

Cơ chế hoạt động:

Tim giãn: van mở → máu từ tâm nhĩ xuống tâm thất

Tim co: van đóng → ngăn máu chảy ngược lên nhĩ

Vai trò:

Giúp máu chảy đúng một chiều trong tim, không bị trào ngược

⚙️ Cơ chế hoạt động 🔹 Khi tâm nhĩ co (đẩy máu xuống thất) Áp lực ở nhĩ > thất → Van mở → Máu chảy từ nhĩ xuống thất 🔹 Khi tâm thất co (bơm máu đi) Áp lực ở thất > nhĩ → Van đóng → Không cho máu chảy ngược lên nhĩ

Giải:

Thời gian người đi xe đạp đi trước người đi xe máy là:

9h40 - 8h = 1h40

1h40 = 5/3h

Khi người đi xe máy xuất phát người đi xe đạp cách người xe máy quãng đường là:

10 x 5/3 = 50/3(km)

Thời gian hai người gặp nhau là:

50/3 : (30 - 10) = 5/6h

5/6h = 1h 10 phút

Hai người gặp nhau lúc:

9h40 + 1h10 = 10h10

Kết luận: Hai người gặp nhau lúc 10h10.

Topic 1: Traffic problems in my city

Traffic in my city is becoming a serious problem. There are too many motorbikes and cars on the roads, especially during rush hours. As a result, traffic jams happen almost every day. The air is also polluted by exhaust fumes. I think people should use public transport more often to reduce congestion and protect the environment.

Traffic in my city is getting worse every year. There are too many motorbikes and cars on the roads, especially during rush hours. Many streets are narrow, so traffic jams happen frequently.
